The thematic strucutre of Duncan's writing is energised by fleeting or 'concrete' dialectical currents. They come in gusts. You can't easily quote from a poem. It's not that you can't show how effective the writing is, but that you can't do justice to the architectural grandeur of the 'whole' piece. He has no fear of embracing the multifarious 'tradition'.
Andrew Jordan in 10th Muse
This clash generates in itself an experience for the reader of strength which is profoundly not power. It comes from a precarious equilibrium-point, not willed and itself formal rahter than psychological or dramatic, at which the limits both of rhetorical drive and counter-sceptical intelligence seem to cancel but actually come to an alignment. The effect, beyond the exhilirating miseries and bloodied metal of locally refused panic, is profoundly strengthening and true.
